! 423: dnl This test is for network applications that need socket() and

! 425: dnl need to link with "-lsocket -lnsl". Under IRIX, they need to link
! 426: dnl with "-lnsl" but should *not* link with "-lsocket" because
! 427: dnl libsocket.a breaks a number of things (for instance:
! 428: dnl gethostbyname() under IRIX 5.2, and snoop sockets under most
! 429: dnl versions of IRIX).
! 430: dnl
! 431: dnl Unfortunately, many application developers are not aware of this,
! 432: dnl and mistakenly write tests that cause -lsocket to be used under
! 433: dnl IRIX. It is also easy to write tests that cause -lnsl to be used
! 434: dnl under operating systems where neither are necessary (or useful),
! 435: dnl such as SunOS 4.1.4, which uses -lnsl for TLI.
! 436: dnl
! 437: dnl This test exists so that every application developer does not test
! 438: dnl this in a different, and subtly broken fashion.
! 439:
! 440: dnl It has been argued that this test should be broken up into two
! 441: dnl seperate tests, one for the resolver libraries, and one for the
! 442: dnl libraries necessary for using Sockets API. Unfortunately, the two
! 443: dnl are carefully intertwined and allowing the autoconf user to use
! 444: dnl them independantly potentially results in unfortunate ordering
! 445: dnl dependancies -- as such, such component macros would have to
! 446: dnl carefully use indirection and be aware if the other components were
! 447: dnl executed. Since other autoconf macros do not go to this trouble,
! 448: dnl and almost no applications use sockets without the resolver, this
! 449: dnl complexity has not been implemented.
! 450: dnl
! 451: dnl The check for libresolv is in case you are attempting to link

! 783: #
! 784: # Of course, Automake must honor this variable whenever it calls a

! 786: # therefore $ac_aux_dir as well) can be either absolute or relative,
! 787: # depending on how configure is run. This is pretty annoying, since
! 788: # it makes $ac_aux_dir quite unusable in subdirectories: in the top

! 790: # relative path needs to be adjusted first.

! 792: # $ac_aux_dir/missing

! 796: # fails when called from a subdirectory in a VPATH build with

! 798: #
! 799: # The reason of the latter failure is that $top_srcdir and $ac_aux_dir

! 801: # harmless because $srcdir is `.', but things will broke when you
! 802: # start a VPATH build or use an absolute $srcdir.
! 803: #
! 804: # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
! 805: # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
! 806: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`

! 812: # configure, and could therefore not use this "fixed" $ac_aux_dir.
! 813: #
! 814: # Another solution, used here, is to always expand $ac_aux_dir to an
